DOOR-HINGE.

Specification of Letters Patent.

Patented June 26, 1917.

Application filed July 28, 1916. Seria1 No. 111,833.

To all whom it may concern:

Be it known that 1,0SOARG. Twnnnnnn, a subject of the King of GreatBritain, residing at Detroit, in the county of Wayne and State ofMichigan, have invented certam new and useful Improvements in DoorHinges, of which the following is-a specification, reference being hadtherein to the accompanying drawings.

his invention relates to door hinges, and

the primary object of my invention is to provide novel hinges that maybe advantageously used in connection with the doors of automobiles,coaches or other vehicles, the hinges including novel means, in a manneras hereinafter set forth, whereby either of the vertical edges of a doormay be swung free of the door jamb thus permitting of a door beingopened to the left or right or bodily removed from the door jamb.

Another object of my invention is to )rO- vide latch held releasablehinge members that may he used upon fire doors or the closures of fireexits insomuch that a fire door may be easily and quickly completelyremoved from its door jamb or frame. A door having such hinge membershas a beveled latch mechanism and irrespective of the manner in whichthe mechanism is actuated, one of the edges of the door is released andto completely remove the door from its jamb, it isonly necessary toagain actuate the latch mechanism. 7

A further object of my invention is to provide door hinges and a latchmechanism wherein the parts are constructed with a view of reducing thecost of manufacture and at the same time retain the features by whichdurability, simplicity of construction, and ease of assembling the partsin a door jamb and door, are secured, and with such ends in View, myinvention resides in a novel construction to be hereinafter specificallydescribed and then claimed.

Reference will now be had to the drawings, wherein- Figure 1 is a frontelevation of a door hinge in accordance with my invention;

ig. 2 is a side elevation of the same;

Fig. 3 is a plan of the door hinge;

Fig. dis a perspective view of a strike plate;

Fig. 5 is an elevation of a door or door frame in accordance with myinvention; and

Fig. 6 is a plan of a portion of an auto- 11 set in the side edgesmobile body provided with a door in accordance with my invention. a

In the drawing, 1 denotes jamb plates carried by the side edges ofa doorjamb or doorway, for instance that of an automobile body, said door jambor body being cut away to permit of said jainb plates being countersunk,also to provide clearance for pintle brackets 3, carried by each of theplates. The pintle brackets 3 vertically aline and are brazed orotherwise connected tothe jamb plates 1, although it is possible tostamp out the brackets from the bodv of each jamb plate. As best shownin Figs. 1 and 2, the pintle brackets 3 are spaced apart at one edge ofeach jamb plate and above the pintle bracketseach jamb plate hasopenings 4 providing clearance for hinged members 5. The hinge members 5are L shaped or angular in plan, and said hinge members have dependingpintles (3 extending through the brackets 3 and supporting the hingemembers thereon, whereby said hinge members may be swung in a lateralplane. Connected to and encircling the lower ends of the pintles 6 arecoiled retractile springs 7 disposed to hold the hinge members 5normally closed. The hinge members 5 associated with each amb plate areconnected by a strike plate having the ends thereof beveled, as at 9,and the central portion thereof provided with latch openings 10. Thestrike plates 8 are adapted to fit in latch or keeper plates of a dooror door frame 12, and as shownin Fig. 5, these latch or keeper platesmay form part of a metallic binder or frame on the edges of the door.The latch or keeper plate 9 have theends-thereof shaped orformed to receive the beveled ends of the strikeplate 8, whereby the strike platemay readily ride inand' out of the latch or keeper plate. Centrally ofthe latch or keeper plate 11 are latch openings 13 for-latches 14, saidlatches being beveled in the usual and well known manner so that thelatches will readily ride into engagement with-the keeper plate, assumeretracted positions, and eventually enter the latch openings 10 of'saidstrike plate to hold or look the strike plate within the latch or keeperplate. The latches 14 have rods 15, slidable in guides 16 and encirclingsaid latch rods are coiled compression springs 17 which hold the latches11 normally extended. The inner ends of the latch rods 15 have pin andslot connections 18 With a cross head 19 on a pivoted lever 20, saidlever being arranged in or without the door or door frame 12 so that thefree end of said lever may be swung to retract either of the latches14:. As shown in Fig. 5, the lever 20 is preferably embodied within thedoor structure and the free end of said lever is exposed at the innerside of the door, whereby the occupant of an automobile may actuate thelever to release either edge of the door to swing in a desireddirection. As shown in Fig. 6, the door has been opened to the right,but as illustrated by dotted lines, it may be swung to the left or maybe bodily removed. To bodily remove the door, first one latch isactuated to allow the door to swing open, and with the door open theother latch is released, thus permitting of the door being removed.

From the foregoing it will be observed that I have devised a door jamband door construction having novel detachable door supporting membersincluding opposed strike plates and opposed latch or keeper plates, thelatter constituting socket members for the former thereby permitting ofa door being easily and quickly hun With the hinge members 5 practicallyintegral and so, also the pintle brackets 7, there is no danger of onepart of the hinge sagging relative to the other, and a door can befurnished with ordinary beads or weather strips to finish out the doorand door jamb connections.

It is thought that the operation and utility of the door will beapparent without further description, and while in the drawing there isillustrated a preferred embodiment of my invention, it is to beunderstood that the structural elements are susceptible to suchvariations and modifications as fall within the scope of the appendedclaims.

hat I claim is l. A door hinge comprising separable strike and keeperplates, and a latch extending through the keeper plate into the strikeplate to hold said plates together so that both of said plates may bemoved in synchronism.

2. A door hinge comprising separable strike and keeper plates, and meanspivotally supporting said strike plate so that said keeper plate may bemoved therewith.

3. A door hinge comprising a jamb'plate,

Copies of this patent may be obtained for a strike plate pivotallyconnected thereto, and a keeper plate to bodily receive said strikeplate.

A door hinge including a frame member having beveled ends, and a doormember adapted to swing in an are on and off of said frame member andhaving beveled ends adapted for engagement with the ends of said framemember to limit the moving on movement of said door member.

5. A door hinge comprising a jamb plate, a strike plate pivotallyconnected thereto, a keeper plate to bodily receive said strike plate,and means holding saidstrike and keeper plates normally together.

6. A door hinge comprising a jamb plate, angular hinge members extendingtherethrough and adapted to swing in horizontal planes, a strike plateconnecting said hinge members, and a door keeper plate at one side ofsaid strike plate and fitted on the ends of said strike plate.

7. A door hinge comprising a jamb plate, pintle brackets carriedthereby, angular hinge m embers extending through said jamb plate andpivotally connected to said pintle brackets to swing in horizontalplanes, a strike plate connecting said hinge members, means adjacentsaid pintle brackets adapted to hold said strike plate normally inparale lelism with said jamb plate, and a door keeper plate inclosingthe greater part of said strike plate.

8. In a door jamb, hinged strike plates at opposite sides of said jamb,a door, and keeper plates at opposite edges of said door adapted to movein a horizontal plane on and off of said strike plates and having alimited moving on movement relative to said strike plates.

9. The combination with a doorof jamb members adapted for supportingsaid door and one of said members remain stationary and independent ofsaid door during a lateral swinging movement of the other membersupporting said door, and door members adapted to bodily receive saidjamb menr bers and move in a horizontal plane on and off of said jambmembers.

In testimony whereof I afiix my signature in the presence of twoWltI16SS6S.
